NIWA scientists have completed another successful voyage to the west coast of the South Island to study the enormous underwater canyon system in the area.
During the 15-day voyage, RV Tangaroa crossed the canyons region collecting mulitbeam bathymetry to map two tributary systems of the Cook/Hokitika canyon system and an additional 400 kilometres of the Moeraki/Haast canyon system.
